A Manhattan federal judge on Friday denied Rudy Giuliani’s request to weigh the constitutionality of search warrants used to carry out an April early morning raid of his home and office amid an ongoing investigation into his dealings in Ukraine.

The ruling, from U.S. District Judge J. Paul Oetken of the Southern District of New York, found that the former New York mayor had cited no legal precedent that would authorize his lawyers to access affidavits for the warrants during an active grand jury investigation.
